フェノール樹脂のケミカルリサイクルプロセス Chemical Recycling Process of Phenolic Resin with Supercritical Fluid Technology
A novel chemical recycling process of phenolic resins was developed. In this process cured phenolic resin was completely decomposed in a very short reaction time, and resin, which was called “recycled resin, ” was recovered in a very high yield by using supercritical or sub-critical mixture of water and phenol as a reaction medium. The recycled resin was used as alternative feedstock of phenol novolac, and materials with the recycled resin had enough properties for practical use. And a demonstration plant was constructed for mass production development.
